Seen your post regarding Sanyo projector http://www.edugeek.net/forums/hardwa...-problems.html
I have Sanyo PLC-XW57 and am having the same problem. Check bulb, and cleaned the filters, they were blocked.
However the projector will power on no image and then go into standby.
Have you ever came across this for this model, is there a thermal switch for this if so do you know where?
No mention about it in the manual.
